Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of rice processing, and in particular to a rice screening device. Background Technology
[0002] Rice refers to the grain after the rice has been hulled. It is an annual herbaceous plant, commonly known as "rice" or "millet" in southern China. During its processing, rice screening devices are often used to screen the rice. Their application is carried out in many key stages such as raw material cleaning and finished product grading, which is of great significance for ensuring rice quality and improving processing efficiency.
[0003] When using screening devices to screen rice, the natural differences between rice varieties can lead to variations in grain size. Furthermore, the purpose of screening varies—it might be to remove impurities or to grade the finished product. Therefore, screens with different mesh diameters are required. This necessitates changing the screening frames according to actual production needs. Changing not only requires stocking a large number of screening frames but also incurs additional equipment purchase and management costs, undoubtedly increasing the overall investment. Moreover, the process of changing the frames requires removing the entire frame, which takes time and impacts worker efficiency. Utility Model Content
[0004] This utility model aims to at least partially solve one of the technical problems in the above-mentioned technologies.
[0005] Therefore, one objective of this utility model is to propose a rice sieving device that, by changing the sieve frame and sieve plate into an independent design, allows for quick replacement of the sieve plate when rice needs to be sieved according to actual conditions, thereby reducing costs while improving replacement efficiency.
[0006] To achieve the above objectives, the first aspect of this utility model provides a rice sieving device, comprising: a support frame, a sieving mechanism, multiple sets of mounting components, multiple discharge pipes, and a bin cover. The multiple sets of mounting components are respectively mounted on the sieving mechanism. The sieving mechanism includes a vibration component, multiple screen frames, and multiple screen plates. The vibration component is mounted on the support frame. The multiple screen frames are respectively mounted on corresponding mounting components. The multiple screen plates are respectively threadedly connected to corresponding screen plates. The multiple discharge pipes are mounted on the outer walls of corresponding screen frames. The bin cover is mounted on the uppermost screen frame.
[0007] In addition, the rice sieving device proposed above according to this utility model may also have the following additional technical features:
[0008] Specifically, the vibration assembly includes multiple limiting posts, multiple springs, a support post, and a driving component. The multiple limiting posts are equidistantly arranged on the bracket, and the mounting assembly is connected to the other end of the multiple limiting posts. The multiple springs are respectively sleeved on the outside of the corresponding limiting posts, and the multiple springs are equidistantly arranged on the bracket, with the other end of the multiple springs connected to the mounting assembly. The support post is arranged on the mounting assembly located below. The driving component is arranged on the bottom wall of the support post.
[0009] Specifically, each set of mounting components includes a base plate, multiple ear plates, a top plate, multiple bolts, and multiple nuts. The base plate is set on the bottom wall of the screen frame; the top plate is set on the screen frame; multiple ear plates are respectively set on the outer walls of the base plate and the top plate; multiple nuts are respectively set on the bottom wall of the corresponding ear plate; and multiple bolts pass through the corresponding ear plate and are pivotally connected to the nuts.
[0010] Specifically, guide bags are installed on the outer walls of multiple discharge pipes.
[0011] Specifically, a material conveying hopper is installed on the silo cover.
[0012] Compared with existing technologies, this utility model has the following advantages: In the rice processing screening stage, the originally integrated screen frame and screen plate are transformed into an independently detachable modular design. When changes occur due to variations in rice variety, grain size, or purity standards, requiring the replacement of screen plates of different specifications to adapt to new screening requirements, operators do not need to perform complex disassembly of the entire screening device. The screen plates can be quickly disassembled and installed using a simple method. On the one hand, only a variety of screen plate specifications are needed to meet diverse production needs, significantly reducing equipment procurement and inventory costs. On the other hand, the rapid replacement operation reduces labor input and lowers energy consumption losses that may occur due to prolonged equipment debugging, achieving the goal of cost reduction and efficiency improvement from multiple dimensions.
[0013] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0019] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.
[0020] The rice sieving device of this utility model is described below with reference to the accompanying drawings.
[0021] like Figure 1 - Figure 3 As shown, the rice sieving device of this utility model embodiment includes: a support 1, a sieving mechanism 2, multiple sets of mounting components 3, multiple discharge pipes 4, and a bin cover 6.
[0022] Multiple sets of mounting components 3 are respectively installed on the screening mechanism 2. The screening mechanism 2 includes a vibration component 21, multiple screen frames 22 and multiple screen plates 23. The vibration component 21 is installed on the support 1. The multiple screen frames 22 are respectively installed on the corresponding mounting components 3. The multiple screen plates 23 are respectively threadedly connected to the corresponding screen plates 23. Multiple discharge pipes 4 are installed on the outer wall of the corresponding screen frame 22. The bin cover 6 is installed on the uppermost screen frame 22.
[0023] The vibration assembly 21 includes multiple limiting posts 211, multiple springs 212, support posts 213, and a driving component 214.
[0024] Multiple limiting posts 211 are equidistantly arranged on the bracket 1. The mounting assembly 3 is connected to the other end of the multiple limiting posts 211. Multiple springs 212 are respectively sleeved on the outside of the corresponding limiting posts 211, and the multiple springs 212 are equidistantly arranged on the bracket 1. The other end of the multiple springs 212 is connected to the mounting assembly 3. The support post 213 is arranged on the mounting assembly 3 located below, and the driving component 214 is arranged on the bottom wall of the support post 213.
[0025] It should be noted that the mesh sizes of the sieve plates 23 described in this embodiment are varied to accommodate different screening requirements, and one of the sieve plates 23 has no mesh to facilitate the collection of screened impurities or objects in the bottom sieve frame 22. The driving component 214 described in this embodiment is a drive motor.
[0026] Specifically, when rice needs to be sieved, the staff can select a sieve plate 23 with a suitable mesh size and connect it to the inner wall of the uppermost sieve frame 22 by thread, thereby installing it into the sieve frame 22. Then, the staff can pour the rice to be sieved into the sieve frame 22. Then, the staff can use the installation component 3 to install the bin cover 6 onto the uppermost sieve frame 22 to prevent rice from splashing out during the sieving process and causing waste of resources.
[0027] Subsequently, the staff can activate the drive component 214 with the help of an external control device. At this time, the drive component 214 will drive the screen frame 22 to shake through 213. The shaking will be transmitted to the spring 212 through the screen frame 22. The spring 212 will deform after being shaken, which will amplify the shaking. The limiting post 211 can limit the degree of deformation of the spring 212. The screened rice and impurities will be discharged through different discharge pipes 4, thus completing the screening of rice.
[0028] In one embodiment of this utility model, such as Figure 2 As shown, each set of mounting components 3 includes a base plate 31, multiple ear plates 32, a top plate 33, multiple bolts 34, and multiple nuts 35.
[0029] The bottom plate 31 is set on the bottom wall of the screen frame 22, the top plate 33 is set on the screen frame 22, multiple ear plates 32 are respectively set on the outer walls of the bottom plate 31 and the top plate 33, multiple nuts 35 are respectively set on the bottom wall of the corresponding ear plate 32, and multiple bolts 34 pass through the corresponding ear plate 32 and are pivotally connected to the nuts 35.
[0030] Specifically, when the screen frame 22 needs to be installed, the worker can install the screen frame 22 onto the top plate 33 on the bracket 1 through the base plate 31, and at the same time align the ear plates 32 on the base plate 31 with the ear plates 32 on the top plate 33. Then, the nut 35 is threaded through the ear plates 32 on the base plate 31 and the corresponding ear plates 32 on the base plate 31 and connected to the nut 35, thereby completing the installation of the screen frame 22. Then, the screen frame 22 and the bin cover 6 are installed one by one in the same way.
[0031] In one embodiment of this utility model, such as Figure 1 As shown, guide bags 5 are respectively provided on the outer walls of multiple discharge pipes 4.
[0032] It is understandable that the guide bag 5 installed on the outer wall of the discharge pipe 4 can prevent splashing during the discharge of sieved rice and impurities, thus avoiding waste of resources or inconvenience in collecting or cleaning them.
[0033] In one embodiment of this utility model, such as Figure 1 and Figure 3 As shown, a material conveying hopper 7 is provided on the hopper cover 6.
[0034] Understandably, through the feeding hopper 7 set on the cover 6, the staff can feed rice into the screen frame 22 through the feeding hopper 7 during the operation of the machine.
[0035] In summary, by transforming the originally integrated screen frame and screen plate into an independently detachable modular design in the rice processing screening process, when changes in rice variety, grain size, or purity standards necessitate replacing the screen plates with different specifications to meet new screening requirements, operators no longer need to perform complex disassembly of the entire screening device. The screen plates can be quickly disassembled and installed using a simple method. On one hand, only a variety of screen plate specifications are required to meet diverse production needs, significantly reducing equipment procurement and inventory costs. On the other hand, the rapid replacement operation reduces labor input and minimizes energy losses that may occur due to prolonged equipment debugging, achieving the goal of cost reduction and efficiency improvement from multiple dimensions.
